A compact gas sensing system using MEMS-based Field Asymmetric Ion Mobility Spectrometry (FAIMS) enables real-time, on-site detection of trace chemicals in air. It visualises temporal and spatial variations in solvents and odours at ppb-level sensitivity, supporting advanced workplace safety, odour control, and air quality monitoring.
